JESSE HARPER BUNDY, OF GREENFIELD, INDIANA.

SWIVEL-JOINT HOSE-COUPLING.

To all whom it may concern:

Be it known that I, Jnssn H. BUNDY, a citizen of the United States, anda resident of Greenfield, in the county of Hancocl and State of Indiana,have invented certain Improvements in Swivel-Joint-Hose-Couplings, ofwhich the following is a specification.

My invention is an improvement in swivel joint hose couplings, and hasfor its object, the pro-vision of a simple, inexpensive and easilyoperated coupling which while preventing accidental longitudinalmovement of the sections of the coupling with respect to each other,will permit their free relative rotation, and wherein the sections maybe easily connected and disconnected, without the use of tools.

In the drawings: Figure 1 is a plan view of the improvement; and, Fig. 2is an enlarged sectional view, taken on the line 22 of Fig. 1.

In the present embodiment of the invention a nipple 1 is provided havinga tapering threaded portion 2 at one end, and an annular external groove3, between the said .portion and the main portion, and an annular rib orflange 4 0n the opposite side of the groove from the threaded portion. Asocket 5 is provided with a bore 6, having an'enlarged portion 7 at oneend, for receiving the main portion of the nipple, and the said end ofthe socket is annularly flanged at 8, the said flange abutting againstthe flange at of the nipple. The end 9 of the socket remote from theflange 4, is reduced, and is connected to the main portion by a taperingportion 10, and the said portion 9 is provided with spaced annulargrooves or corrugations 11, for permitting the attachment of the hose. Aretaining sleeve 12 encircles the socket, and a coil spring 13 encirclesthe socket, between the adjacent end of the sleeve and the flange 8, Theinner end of the sleeve is annularly flanged at 14, and

r the said sleeve is provided with oppositely arranged radial pins 15,adjacent to the 'flange 14.. A casing or lock sleeve 16 incloses thespring and the inner end of the retaining sleeve. The outer end of thesaid sleeve 16 is provided with an internal flange Specification ofLetters Patent.

nipple and socket. Each of the slots 18 eonsists of a portionlongitudinal to the nipple, a portion transverse to the nipple, and anotch or recess 19 at the end of the said portion for engagement by thepins to lock the parts from rotation.

The parts may be easily released by pressing the sleeves toward eachother, until the pins 15 are released from the recesses 19. The sleevesare then rotated slightly with respect to each other, until the pins 15enter the inner portions of the slots, when the spring 13 forces thesocket away from the nipple.

The nozzle 20 is threaded onto the portion 2 of the nipple, and it willbe evident that the said nozzle and nipple may rotate freely withrespect to the socket. The spring prevents the possibility of accidentalunlocking of the parts. The nipple. and the socket are the couplingsections, and each section has a sleeve journaled thereon and providedwith means for preventing the section from movement in outward directionaway from the other section, and the socket is yieldingly connected withits sleeve.

It will be noted that the improvement is especially adapted for use inthe operation of pneumatic hammers, on account of the absence of theusual elastic packing.

I claim:

A device of the character described, comprising a nipple having athreaded portion at one end for engagement by a nozzle and having anannular rib intermediate its ends, a sockethaving one end reduced forengaging the hose, and being internally enlarged at the other end to fitover the nipple, said socket having an annular flange at the endadjacent to the rib and fitting against the said rib, a retaining sleevefitting over the engaging the rib on the opposite side from socket andhaving a lateral flange at its the socket flange, and having bayonetslots outer end, and oppositely arranged pins adfor engagement by thepins.

jacent to the flange, a spring encircling the JESSE HARPER BUNDY. 5socket between the sleeve and the flange of Witnesses:

the socket, and a locking sleeve fitting over JOHN H. BROOKS,

the spring and having an internal flange C. W. GANT.
